30 years… When Sigma was founded, I admired it. Its founders had left the comfort of a public research laboratory to confront the harsh realities of the consulting profession. But I was confident, impressed by the team’s enthusiasm and strategic vision… and I was right, because today Sigma Orionis has become a beautiful star in the galaxy of consultancy. I am delighted to have contributed, if only modestly, to this brilliant success!
